UNITED STATES PATENT OFFICE.

To all whom it may concern:

Be it known that I, FRANK M. KRASMER, a citizen of the United States of America, residing at Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification.

This invention'relates to new and useful improvements in wagons, and relates more particularly to that class known as"chu-tewagons and it has primarily for its Object to present novel means whereby the body may be elevated.

It is a further object of the invention'to provide a novel device of this character wherein means are provided for regulating or controlling the elevation of the body.

With the foregoing and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter. more fully set forth and claimed.

In describing the invention in detail reference will be had to the accom anying drawings, forming part of this specificatiomwherein like characters denote corresponding parts in the several views, in which- Figure 1 is a side elevation of a dumpingwagon embodying the invention. Fig. 2 illustrates a front view thereof. Fig. 3 is a detail view illustrating a slightly-modified construction. Fig. 41s a fragmentary enlarged detail view.

In the drawings, 1 denotes a front truck, and 2 a rear truck, connected by the sills 3, on Journaled on the sills 3 is a transversely-arranged shaft 5, which is provided on one end with a gearing 6, which meshes with a suitable gearing 7, which is provided witha crank 7 or other suitable means. It is to be stated that as the gearing forms no essential feature of the invention detail thereof is omitted, as any means may be employed which will easily rotate the shaft 5. Pivotally secured to the sills 3, near one end thereof, are the levers 8, said levers being also pivoted to the body 4 at points approximately midway the length thereof, and said levers are provided with depending ears 9, said ears being positioned near the upper end of the levers, or that end of the levers secured to the wagon-body. Keyed to the shaft 5 are arms 10, which have on their free ends parallel projections 11, between which are pivoted the ends of the arms Specification of Letters Patent. Applicationfiled February 9,1906. Serial No. 300.273.

12. The opposite ends of'the arms 12 arel pivoted to the ears 9 of the levers 8. When the shaft 5 is rotated, the arms 10 are lifted upward, which causes the body 4 to elevate. This upward motion of the arms will continue until the arms" 12 have been fully extended, This point is the limitof the upward movement of the body. A device constructed in this manner is of few parts and of a very simple construction; but in practice it has been found most advantageous and highly efficient.

In order to control the movement of the body 4 on the levers 8, a controlling rod or regulator 13 is interposed between the wagonbody near its front end and the shaft. This PatentedSept. .11. 1906.

regulator comprises at its upper end a yoke 14, which is pivota'lly secured near the front end of the body. Centrally of the yoke down to the shaft 5 is a flat rod 15. The lower end of the rod is .bent around the shaft and extends upward a short" distance, as at 16. Through the'rod 15 and the turned-back portion 16 is a series of registering perforations, through which a pin 17 is inserted.

When the body has been raised, its up ward movement on its pivotal connection with the levers will be limited by said rod 15, and the angle of its incline will be controlled by the adjustments of the pin through the perforations at the lower'end of said bar or rod. It is to bealso mentioned that the rod '15 holds'the front of the wagon in its elevated position as will, it is thought, be fully appreciated from an inspection of the drawin s.

In Fig. 3 is illustrated a modified connection between the hoisting-or elevating arms a and the link I). The upper end of the arm a is provided with a lug or extension 0, extending at right angles thereto. This extension is adapted to fit within a bifurcated end of the link I). A pivot-pin passes through the bifurcated portion and lug. The pins are arranged beyond the center of the links I). This means allows the opposing ends of the arms to contact when elevated at the highest point, and thereby relieves the strain from the pivotal pin. It is to be understood that the inner wall of the forked or bifurcated end of the link 1) comes into contact with the outermost surface of the right-an gular extension. 0 of the arm (1, thereby limiting the movement of the arm a and at the same time relieving the stress upon the pin. The abutting ends will also limit the upward movement of the arms.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination, suitably supported sills, a shaft mounted on the sills, a body, means operated by the shaft for elevating the body, a connection between the shaft and an end of the body to limit its movement, and means for operating the shaft. 7 2. In combination, sills, a shaft mounted on the sills, a body, means operated by the shaft for elevating the body, an adjustable connection between the shaft and an end of the body to limit its movement, and means for operating the shaft.

3. In combination, suitably-supported sills, a shaft journaled on the sills, arms on the shaft, a body, levers pivoted at one end to the sills and at the opposite end to the body, connections'between the levers and the arms of the shaft, and means for rotating the shaft. t

4. In combination, suitably-supported sills, a'shaft journaled on the sills, arms. on the shaft, a body, levers pivoted atone .end to .the sills and at the opposite end to the body, connections between the levers and the arms of the shaft, means for rotating the shaft, and means actin in conjunction with the body and the shaft for limiting the movement of the body on it's pivotal connection with the levers.

5. In combination, suitably-supported sills, a shaft journaled on the sills, arms on the shaft, a body, levers pivoted at one end to the sills and at the opposite end to the body, connections between the levers and the arms of the shaftfmeans for rotating the shaft, a rod pivotally secured to the body near one end and pivotally held by the drivsuitably supported I ing-axle for limiting the movement of the body on its pivotal connection with the levers.

6. In combination, suitably-supported sills, a shaft journaled on the sills, arms on the shaft, a body, levers pivoted at one end to the sills and at the opposite end to the body, connections between the levers and the arms of the shaft, means for rotating the shaft, and a rod interposed between one end of the body and the driving-axle, the end adjacent the body being provided with a yoke pivotally secured to the body, while the opposite end is bent back upon itself to embrace the driving-axle, and means for looking the rod to the axle.

7. In combination, suitably-supported sills, a drivingshaft thereon, arms carried by the shaft, a body, levers interposed between the body and the sills and pivoted thereto, links pivotally secured to the levers at one end and at the opposite end to the arms of the axle, and means for rotating the axle.

8. In combination, suitably-supported sills, a driving-shaft thereon, arms carried by the shaft, a body, levers interposed between the body and the sills and ivoted thereto,

links pivotally secured to t e levers at one end and at the opposite end to the arms of the axle, means for rotating the axle, the links being so pivoted to the arms that when the arms are elevated, the strain on the links is thrown on the arms roper.
